Install the SYNCHRONO module

This is an optional module that enables the paralellization of Chrono::Vehicle simulation across MPI computing ranks.

Read the introduction to modules for a technical background on the modularity of the Chrono project.


The SynChrono module allows users to paralellize the dynamics computations for Chrono::Vehicles across MPI ranks

Required Dependencies

  • To build applications based on this module, the following are required:
    • MPI - Tested with OpenMPI and MPICH on Linux and with Intel MPI and MS-MPI on Windows. NOTE: On Windows please ensure that the MPI dll (either impi.dll or msmpi.dll) is on your system path, for example by running a post-installation script (Intel MPI example).
    • FlatBuffers - A version is included in chrono_thirdparty as a submodule but a separately-installed version (for example through a package manager) will work as well.

Building instructions

  1. Repeat the instructions for the full installation. The Chrono::Vehicle is required and at least one of Chrono::Irrlicht or Chrono::Sensor is recommended for visualization. When you see the CMake window, you must add the following steps:
  2. Set the ENABLE_MODULE_SYNCHRONO as 'on', then press 'Configure' (to refresh the variable list)
  3. If Flatbuffers is on your system path (for example package-manager installed versions), then CMake may pick it up automatically. Otherwise set Flatbuffers_DIR to the CMake folder within your Flatbuffers installation (for example ../src/chrono_thirdparty/flatbuffers/CMake) and set Flatbuffers_INCLUDE_DIR to the include directory within your Flatbuffers installation (for example ../src/chrono_thirdparty/flatbuffers/include).
  4. Press 'Configure' again, then 'Generate', and proceed as usual in the installation instructions.
